Title: Improvements in or relating to flow control valves
IPC: F15C3/02
Filed: 1958-03-04
Abstract: 875,325. Fluid-pressure servomotor control systems; valves. FORD MOTOR CO. Ltd. March 4, 1958 [March 21, 1957], No. 5394/61. Divided out of 875,324. Class 135. A flow control valve 10 adapted to control the flow through a fluid delivery passage, such as the exhaust pipe of a servo-operated brake actuating a low gear drive in an automatic car transmission described in Specification 875,324 comprises a valve chamber, a movable valve element disposed within the chamber and including two valve lands 13, 14 having inner opposed faces of different areas, a pre-calibrated orifice 15 situated in the passage, the outer face of the valve land 14 being subject to the pressure of the fluid on the downstream side 12 of the orifice and the outer face of the valve land 13 being subject to the pressure of the fluid on the upstream side 11 of the orifice, a valve port in the wall of the valve chamber and interposed in a part of the passage which passes through the chamber, the valve land 14 being adapted to progressively restrict the port upon movement thereof in one direction, application of a control signal pressure to the opposed inner faces of the valve lands tending to urge the valve element in the said one direction, and the resultant force produced by the fluid pressures in the passage urging the valve element in the opposite direction. As described in Specification 875,324, the valve 10 is arranged to prevent the servo-operated brake from being engaged when the car is travelling at high speed, a speedcontrol signal pressure being fed to the opposed inner land faces to close off flow through the port, the brake being normally held open by the fluid pressure.

Abstract: 1378173 Fluid pressure control of brakes W T TEAGLE 1 March 1972 [1 March 1971 1 Dec 1971] 5648/71 and 55754/71 Heading F2F  Trailer brakes are rendered fail-safe by making them spring-applied at 1 and released by hydraulic pressure from the tractor source 48 subject to control by a manually operable valve 45 having a ball valve 6 which is adjustably spring-loaded by a cam 12 operated by lever 14. The valve adjusts the leak-back over line 7 to the pressure source and this leak also ensures automatic brake application in the event of the engine stopping. As shown,- a multi-outlet valve 46 is provided on the tractor to cut off trailer brake-pressure, to apply its brakes, during tipping by feeding rams 53. In the form of slave cylinder 3 shown, the brake-applying spring acts on the rear side of the piston, but it may lie outside the cylinder (Fig. 3, not shown) and act on a separate linkage. Alternatively, it may be replaced by Belleville washers (Fig. 4, not shown) or placed in the slave cylinder of a dual hydraulic system (Figs. 7 and 8, not shown). Adjustment by a conventional tensioner may be facilitated by a projection on the piston which dislodges a ball valve in its de-energized position to vent any remaining pressure. Each wheel brake may be mechanically operated by a separate piston incorporating an adjuster.

[Class 135] [See also Group XVII] A tap for metal containers comprises a bayonet 15 sharpened on both edges for cutting a circular hole into which a threaded part 14 of a body 10 screws, a rubber &c. gasket 12 ensuring a tight joint. A spout 13 and vent hole 16 are provided opposite to each other on the body 10, a cylindrical valve member 17 held by a set-screw 18 and a groove 19, and actuated by a handle 20, serving to open and close the spout and to move a ball 26 into and away from the vent by means of a cam groove 25. A vent passage 24 communicates with the interior of the container. If the container itself is provided with a vent, an additional turning of the valve will re-seat the ball in the tap vent so that liquid will not emerge through this. A bridge 28 extending over the aperture 21 in the valve prevents the ball from escaping from its groove. A washer 22 forms a tight joint between the valve cylinder and the body 10.

Patent GB-452579-A (GB)
Title: Manufacture of fluorinated organic compounds
IPC: C07C51/363
Filed: 1935-02-25
Abstract: Fluorinated carboxylic acids are obtained by addition of hydrogen fluoride to compounds containing at least three carbon atoms, at least one carboxyl group, and at least one treble bond. Two molecules of hydrogen fluoride may be added at the treble bond, with the production of saturated compounds, or only one molecule may be so added, olefinic compounds being then obtained. The reaction may be effected at atmospheric temperature and pressure in the presence or absence of a solvent, e.g. methylene chloride or carbon tetrachloride.  An example is given in which stearolic acid is treated with gaseous hydrogen fluoride to yield 9 : 10-difluorostearic acid.  Other specified starting materials are acetylenedicarboxylic acid and phenylpropiolic acid.  The fluorinated acids may be converted into their esters or amides. The products are useful as fungicides, insecticides, disinfectants and assistants in the textile industry, and if insoluble in water they may be used in the form of emulsions.
